Introduction
Starting back in the early 1990's with the introduction of Java to the computer scene there has been many updates and advances in how languages interact with web based programs. In this paper we are going to highlight several areas of several different Java flavors. The flavors we are addressing are Java, JavaScript, Java Applets and JavaBeans. We will discuss their history, features, usage and syntax and finally follow up with a chart providing a comparison of the different Java architectures. History

Java, a language based on C++, was developed by James Gosling and colleagues at Sun Microsystems in the early 1990's. (Java programming language, n.d.) It was originally called OAK and was designed for set top boxes and hand held devices. "Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web." (Java, n.d.) Java is an object-oriented language simplified to eliminate language features that cause common programming languages. Java should not be confused with JavaScript, which shares only the name and a similar C-like syntax. Sun Microsystems currently maintains and updates Java regularly. JavaScript was designed in April 1995 by Brendan Eich. It was initially developed under the name Mocha, then LiveScript and finally settled on JavaScript, coinciding with the addition of Java support in the Netscape web browser. (JavaScript, n.d.) "Spawned in 1995 by the need to make Netscape Navigator's newly added support for Java applets more accessible to non-Java programmers and web designers, a powerful scripting language too often described as ‘simple'." (Champeon, 2001) "Netscape developed Javascript in 1995 as a way for web server administrators to connect their servers to databases and search engines, and on the client side for validating forms and providing interactive content on the HTML level." (The History of Java, n.d.) JavaScript was originally known as LiveScript because of its dynamic nature. JavaScript was commonly used to manipulate images and document contents.

There were early issues with JavaScript; security flaws, lack of development tools and often criticized for "being too unlike Java, or too much like Perl." (Champeon, 2001) However, JavaScript took on a life all its own and in some circles was written off due to its simpleness, its security flaws and to some extent because it could only be tested within the browser environment. A Java Applet is a small program written in Java, which can be downloaded to any computer. The applet is usually embedded in an HTML page on a Web site and can be executed from within a browser. "JavaSoft, the current name of the company which oversees the development of the Java language, was founded in January of 1996, and a few months later released the Java Development Kit (JDK) version 1.0." (Youmans, 1997) The concept of an applet came out of the creation on the Java language. "It enabled users to produce programs named applets which could be transmitted and run over the Internet, a somewhat different end product from what was originally envisioned back at the beginning of the decade." (Youmans, 1997) Java Applets came about as a requirement for adding functionalities to HTML documents, especially in the Graphical User Interface (GUI) area. Applets are essentially small programs that are embedded within a web page and run within the pages' web browser environment. Java Beans are a specification developed by JavaSoft that defines how Java objects interact. An object that conforms to this specification is called a JavaBean, and is similar to an ActiveX control. It can be used by any application that understands the Java Beans format. JavaBeans are written in the Java programming language. Like ActiveX controls, JavaBeans components are reusable software programs that you can develop and assemble easily...
